Get things done with ultradian sprint

It has been statistically proved that distractions are costly: A temporary shift in attention from one task to another – stopping to answer an e-mail or take a phone call, for instance – increases the amount of time necessary to finish the primary task by as much as 25%, a phenomenon known as “switching time”. It’s far more efficient to fully focus for 90 to 120 minutes, take a true break, and then fully focus on the next activity. We refer to these work periods as “ultradian sprints.”
